with python, i want to create point feature class. how to create point in specified coordinate but not from a file which contain coordinate. i have try to make the script but there was an error " 'list' object is not callable. ". anyone have an explanation? # Process: Add Field... gp.AddField_management(InputFC__2_, "V", "DOUBLE", "", "", "", "", "NON_NULLABLE", "NON_REQUIRED", "") # Process: Calculate Field... gp.CalculateField_management(InputFC, "V", " * ", "VB", "") # Process: Summary Statistics... gp.Statistics_analysis(InputFC__3_, InputFC_Statistics_dbf, "D SUM;V SUM", "") # create the output feature class using the spatial reference object gp.CreateFeatureClass(New_Folder,OutputFC,"Point","ENABLED","DISABLED",spatialRef) gp.AddField_management(OutputFC,"D","DOUBLE","", "", "", "", "NON_NULLABLE", "NON_REQUIRED", "") gp.AddField_management(OutputFC__2_,"H","DOUBLE","", "", "", "", "NON_NULLABLE", "NON_REQUIRED", "") rows = gp.SearchCursor(InputFC_Statistics_dbf) row = rows.Next() while row: count1 = row.SUM_V count2 = row.SUM_D prows = gp.InsertCursor(OutputFC__3_) # create point object to create feature pnt = gp.CreateObject("Point") pnt.id = 1 pnt.x = 566020 pnt.y = 252044 prow = prows.NewRow() prow.Shape = Point prow.Dt = count2 prow.H = count1 / count2 Point.Add(pnt) prows.InsertRow(prow) row = rows.Next() del prow, prows del row, rows ...

i want to create point feature class... but there is an error when this script ran at arcmap 9.3.. (error 999999 : error executing function.
